Runner's World Review

The retro design of the 400 brings the foot closer to the ground and does so without the supportive structures of modern trainers. It uses a mix of rubber and foam in the sole that holds up well but isn't as grippy as more standard rubber-only soles. The shoe's banana-shaped bottom assists the roll of the foot from heel-strike to toe-off. Shoe Lab results reveal cushioning that's sufficiently soft for heel-and forefoot-strikers and not too mushy. The 400 is a first-rate distance trainer for average to lightweight runners.
